WHAT'S IN YOUR EARS??

I've written that I enjoy listening to my ipod while I walk - unless I'm walking with a buddy. What do YOU listen to?

ipod or other source of music
ipod or other source of talk - radio or book
walking buddy in person
walking buddy on the cell phone
sounds of nature
what else??

So, please share what's in your ears while you're walking?

Remember my 100% GUARANTEE. Should you decide to stop walking and resume your old habits, I personally guarantee that you'll get back 100% of your former life - your pain, your lifestyle, your attitude.
